The cost for driving a single lap of the Nordschleife is €21 for each car or motorcycle. Multi-lap tickets can be purchased for a lower per-lap price, such as 4 laps at a cost of €70 (€17.50 per lap). Additional multi-lap prices are 8 laps for €135, 15 laps for €235, or 25 laps for €370

Its not expensive, a lap of the Nurburgring is PRICELESS!!!

best money spent I bet, hope to get to do it sometime in my lifetime!
How long did the whole lap take?
